We claim as our invention:

1. In a device of the class described, the combination with a guideway from which sheets are successively ejected in a substantially horizontal plane, of a duplex tray for receiving and automatically stacking the sheets on edge and substantially out of contact with each other except at their top edges, comprising an inverted V-shaped partition member the top edge or ridge of which extends forwardly from said guideway, and outwardly and upwardly curved shelves re spectively continuous With the lower edges of the limbs of said partition member onto which the sheets fall edge foremost, the concave upper faces of said shelves automatically spacing the lower edges of the sheets as the latter fall thereon, and means for supporting said tray with capacity for adjustment laterally to bring the top edge or ridge of said partition to one side or the other of the transverse center of said guideway.

2. In a device of the class described, the combination with a guideway from which sheets are successively ejected in a substantially horizontal plane, of a duplex tray for receiving and automatically stacking the sheets on edge and substantially out of contact with each other except at their top edges, comprising an inverted V-shaped rectangular partition member, the top edge or ridge of which extends forwardly from said guideway, outwardly and upwardly curved shelves respectively continuous with the lower edges of the limbs of said partition member onto which the sheets fall edge foremost, the concave upper faces of said shelves automatically spacing the lower edges of said sheets as the latter fall thereon, means for supporting said tray in a downwardly and forwardly inclined position with capacity for adjustment laterally to bring the top edge or ridge of said partition to one side or the other of the transverse center of said guideway, and a stop member for the sheets straddling the top edge of said partition.

3. In a device of the class described, the combination with a printing machine frame having a guideway from which printed sheets are successively ejected in a substantially horizontal plane, and a transverse horizontal rod underlying the forward end of said guideway, of a duplex tray for receiving and automatically stacking the sheets on edge and substantially out of contact with each other except at their top edges, comprising an inverted V-shaped partition member the top edge or ridge of which extends forwardly from said guideway, outwardly and upwardly curved shelves respectively continuous with the lower edges of the limbs of said partition member onto which the sheets fall edge foremost, the concave upper faces of said shelves automatically spacing the lower edges of the sheets as the latter fall thereon, means for supporting said tray in a downwardly and forwardly inclined position with capacity of lateral adjustment to bring the top edge or ridge of said partition to one side or the other of the transverse center of said guideway comprising a bar extending between and attached to the limbs of said partition and having a notched rear end slidably engaged with said rod, and a stop member for the sheets straddling the top edge of said partition.
